No audio in Flash content: Workaround

Several readers have reported an issue where embedded Flash content (such as the videos on YouTube and other services) does not contain audio. In other words, the video playback works as expected, but no sound accompanies it.

This problem is usually caused by an erroneous Audio Output setting. While the causes for this value being changed to a problematic setting are varied, the fix is simple:

1. Launch Audio MIDI Setup (/Applications/Utilities/)
2. Click on the "Audio Devices" tab at the top of the Window
3. From the "Properties For:" pull-down menu, select "Built-in Output"
4. Change the Audio Output setting to 44100.0 Hz
5. Quit Audio MIDI Setup

Quit then re-launch your Web browser, or the media player in which you are accessing the afflicted content and re-check for sound output.
